Traveling Salesman / News: Recent posts

The way start and end -points for routing
are selected has been improved with the new
PlaceSelectionPanel.
This was required for the upcomming introduction
of search-plugins, a plugin-infrastructure
and searching via the OSM-name-finder.

Adding GPS-support for routing "from here" will
be made possible by this.

You will be able to search for 2 places and
the maps of these regions are downloades as
needed.

You can now drag the mouse with the right
mouse-button and zoom in/out using the scroll-wheel
like in JOSM.

The default map-renderer has been improved big time.
It can now draw and fill different typed of roads,
waterways and areas with different colors, borders and stroke-width. Thus making the map much easier to read.

Traveling-salesman now displays simple
driving-instructions.
For this to work a new panel was added
and some bugs ragarding street-names fixed.

Displaying the map was finaly implemented.
After numerous problems with having Batik
render the nice SVG-output of Osmarender
we resolved to using some JOSM-code to
at least render a simple graph of the map.
It was modified to remove "selected items"
as this is no editor and to mark a route.

You can also download the currently visible
area (e.g. afte zooming out) directly from
OpenStreetMap.

The Wiki has been updated big-time.
It now links to the Javadoc of all 3 sub-projects,
lists the most-important classes (to find your way around the code quickly) and
references the source-codes in ViewSVN to
have a look at the details.

libosm and osmnavigation:
There where a lot of linear lookups in the first (test-)version. They have now been changed into
Hashtable-Lookups and local caching.
This improved the DirectedDepthFirstRouterTest from
3.6 seconds down to 7ms .
Now it has a speed we can do real routing with.

traveling-salesman:
No work on the traveling-salesman-UI yet, my eclipse keeps crashine.

libosm:
No time yet to upgrade to the newer osmosis-version that Brett released.

The switch of the codebase to osmosis 0.9-mw1 is nearly done.
Everything compiles again and the one of the 2 navigation-unit-tests is working again.
Now it is time for cleanup and the introduction
of hashmaps, keys and parallel execution to speed things up.

We submitted our first SVN-Code.
We have a working route-finder and
can load maps from the OpenStreetMap-Server
as well as describe our routes to a user.

However rendering maps and storing the downloaded
map in a local database is not yet fully implemented.

We are also still setting up the web-page and wiki.

..stay tuned
